GENERATION OF ELECTRON BEAMS IN MAGNETRON GUNS WITH SECONDARY EMISSION CATHODES OF A SMALL DIAMETER

摘要

This paper is concerned with investigations on electron beam generation in magnetron guns with cold secondary-emission metallic cathodes of a small diameter with a large aspect ratio. The parameters of electron beams are given as a function of electric and magnetic field values using different methods of voltage pulse formation for secondary-electron multiplication and beam generation.
